Marine Planning

Background—Ocean Uses

Background—Ocean Uses

  • Carefully planning is required to minimize conflicts and foster compatibilities among uses
  • This planning process is termed marine spatial planning,
  • MSP has been developed worldwide from coastal to open-ocean regions
  • It focus as a way to foster sustainable ocean management and governance.

Ocean Challenges

Current Situation

Current Situation

  • Marine scientists face a challenge of synthesizing and communicating information from large and complex data sets.
  • Growth in data and advance in computational, can make the process of communicating the results to decision makers in a meaningful way.
  • The traditional approach of presenting information across a series of static slides and plots often fails to convey the richness of information available.

GAP

Existing

  • Static
  • Difficult to update

Opportunity

Tools for interactive visualization

  • Interactive maps
  • Interactive plots
  • engage users and stakeholders
  • easy to update the information
  • backend serve as database

Tools for Effective MSP

Tools for MSP

  • ocean management requires the integration and analysis of large and diverse data sets
  • reproducible, and collaborative tools are needed to analyze, visualize, and update data in an efficient and cost-effective manner.
  • Overcome the inherited challenge of traditional static outputs (e.g., tables, figures, reports, maps)+

Interactive tools

  • Interactive plots combined with spatial tools are effective way to communicate information used to inform decision-making processes such as

    • stock assessment,
    • ecosystem approaches to fisheries management,
    • conservation planning, and
    • marine spatial planning.

Interactive Tools

  • Interactive tools allows
    • The audience to interact with data and data products,
    • users to control over type of information
    • Users to download, filter, and re-plot the data to their desired test
    • Provide room to work in a more open and transparent manner.

R languages for MSP

  • R programming language has grown into a software that offers tools to build interactive tools for effective communication
  • These web apps web applications are increasingly being used to explore research interactively.

Packages

Interactive tools building dashboard

  • Flexdashboard—R package provides structure and containers where information will be placed
  • Plotly— This package supports the creation of interactive graphics

  • Shiny —

  • Crosstalk—the package enables cross-widget interactions by linking, brushing, and/or filtering across multiple views.

Conclusion

  • The marine planning efforts should be flexible and adaptive to potential future alterations
  • Regional and national policies should incorporate change to thrive in a dynamic and uncertain future.
  • Regular update mechanisms must be established.
